A few minutes after audio input signals cease, the Subwoofer automatically returns to standby mode. POWER INDICATOR LED This LED is unlit when the AC power switch is OFF. It glows red when the Subwoofer is in standby mode ad green when the Subwoofer is on. FUSE 250V 2A This fuse protects against internal and external faults. If the POWER switch is ON and the power indicator LED is unlit, unplug the power cord from the AC and the back of the amplifier, then pry up the rectangular fuse holder and check the fuse. IMPORTANT If the fuse is blown, replace it only with a fuse of the same type and current rating. L, R SPEAKER OUT & IN - See Connection Option 1 These terminals are for making connections using speaker wire. If you use this option, do not use Option 2. LINE IN & LINE OUT - See Connection Option 2 These are for connections using audio cables. If you use this option, do not use Option 1. LOW PASS FREQUENCY CONTROL Adjusts the upper frequency limit for audio sig- nals going to the Subwoofer amplifier. This control helps you adjust the system’s tonal balance. LEVEL CONTROL Balances the loudness of the Subwoofer relative to the Front speakers and compensates for room effects on the Subwoofer’s output. PHASE SWITCH The Phase Switch controls the phase of the Subwoofer’s output relative to the front speakers. Listen carefully to the sound quality while playing a CD with low bass. Select the position of the switch that produces the fullest deep bass without boominess. You may need to readjust the Level and Low Pass Frequency controls after setting the Phase Switch. CONNECTING YOU SUBWOOFER IMPORTANT: When you make connections. make sure that the power switches of all components, including the Subwoofer, are OFF. AUDIO CABLES If you are connecting the Subwoofer into a system made up of separate components (preamp & power amps), you will need audio cables long enough to reach the Subwoofer from the preamplifier and the power amplifier. SPEAKER WIRE Typical speaker wire has a pair of separate conductors with insulating jackets that are molded together. We recommend that you use 16-gauge speaker wire for hooking your Receiver to your Front speakers. To make connections to the Subwoofer in parallel with the Front speakers easier, the speaker wire connecting the Receiver to the Subwoofer can be smaller (higher gauge number), since the Subwoofer does not draw large amounts of power through these wires. POLARITY All speakers in a system must be connected with the same polarity. Speaker wire is marked for polarity so that you can identify which wire in the pair is which. Polarity is shown by a color strip on the insulation, by ridges molded into the insulation, or by the colors of the wires - one copper and one silver. Strip the insulation from speaker wire ends to reveal the bare conductors before connecting to Receiver, Subwoofer or Speaker terminals. IMPORTANT Always connect the red + terminal on the Receiver to the red + terminal on the Subwoofer, and the black - terminal on the Receiver to the black - terminal on the Subwoofer. The same is true for hooking the Receiver outputs to the Front speakers: red + to red +, and black- to black-. IMPORTANT USE OPTION 1 OR OPTION 2, NOT BOTH. OPTION 1 – CONNECTION WITH SPEAKER WIRE Connect speaker wires from the Receiver’s front left and right speaker outputs to the Subwoofer’s Speaker Level-In connections. Connect left channel to left input and right channel to right input. You have the option of connecting your main speakers to the speaker B outputs on your Receiver, if it is so equipped or you also have the option of connecting your main speakers using the connections on the Subwoofer. This will pass the audio signal to your main speakers, except the low bass which will be produced by your Subwoofer. To use this connection option, connect your main speakers to the right and left outputs on the Subwoofer (see illustration 1). Be sure you take care to main- tain proper signal polarity, red to red and black to black. OPTION 2 – CONNECTION WITH AUDIO CABLE Connect a pair of audio cables from the preamp’s output jacks to the subwoofer’s LINE IN jacks. Connect left channel to left to left and right channel to right. Connect a pair of audio cables from the subwoofer’s LINE OUT jacks to the power amplifier’s input jacks. Connect left channel to left and right channel to right. If your preamp receiver or processor has a subwoofer or mono output jack that is controlled by the master volume control, use a single audio cable to connect that output to the subwoofer’s Line-In jack. No audio cables from the subwoofer’s Line- Out jacks are needed in this set-up.
